Also, get familiar with Ohio landlord laws around notice periods, eviction timelines, and security deposits—they can differ from CA.

Tenants don't care nearly as much about issues as you do and will often forget to take any of these actions.If your tenants notice a pipe that is frozen, tell them to make sure they leave faucets on.

I've noticed 3 layers to this when I speak with my subs or even other GCs in the past: They have the knowledge, or they don't.

In Wisconsin the tenant gets additional protection and longer deadlines on some notices.

I don't think I noticed the others doing the same because they were so over the top ridiculous I'd instantly tune out.

One thing I've noticed - most investors are so focused on finding the perfect STR deal they miss the obvious play: building relationships with local property managers who already manage STRs.

I did notice that we can use wild cards in the search, but after I figure that out I stopped playing with it for a time.

Fair housing, security deposit laws, notices, lease wording, handling maintenance correctly.

As my portfolio has grown, I’ve noticed that while self-managing makes sense, it also starts to feel messy and time-consuming in ways that aren’t always obvious at first.I’m not selling anything, just looking to connect with other landlords who self-manage and hear about the parts of the process you find most frustrating or inefficient.At what point did self-managing start to feel harder for you, and what do you find most annoying about it today?
